ABSTRACT:
A color image signal is generated and an arbitrary color in the color image signal is set as a color to be converted. A color after conversion is designated. The color to be converted or a color similar to the color to be converted is converted into the color after conversion or a color similar to the color after conversion. By this processing, a color-converted image, in which a conversion boundary is unnoticeable, can be produced.
